【问题描述】：
为 rtmidi-python 构建轮子的 PIP 失败（子进程退出错误和遗留安装失败）
大家好，我在运行 Raspbian 11 的 Raspberry Pi 4B 上安装 rtmidi-python 时遇到了 pip 问题。
构建轮仅针对该软件包一直失败，我收到两个错误：subprocess-exited-with-error 和 legacy-install-failure。
这是命令 pip install rtmidi-python 的输出：
pi@raspberrypi:~ $ pip install rtmidi-python

╰─> rtmidi-python
note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.
Pip (22.0.4) 和 Python (3.9.2) 是最新的。
我尝试从 PyPI (https://pypi.org/project/rtmidi-python/#files) 手动下载软件包以使用 python setup.py install 安装它，但它似乎没有安装任何东西：
这是输出：
pi@raspberrypi:~/Downloads/rtmidi-python-0.2.2 $ sudo python setup.py install

Writing /usr/local/lib/python2.7/dist-packages/rtmidi_python-0.2.2.egg-info
对于某些人来说，这可能是 setup.py 的问题，但我不知道更多。 我一直在寻找大量论坛上的解决方案，但没有成功。我们将不胜感激。
谢谢大家。
